PERMISSION IS HEREBY GRANTED TO
EMRD Marketing Company
Cabarrus County
FOR THE
construction and operation of a groundwater remediation system consisting of eight vacuum/recovery
wells, an oil/water separator, an aerated holding tank, an air stripper, carbon absorption unit, and a 13,500
square foot infiltration gallery to serve Speedway Unit #102 with no discharge to the surface waters,
pursuant to the application received January 9, 1992, and in conformity with the project plan,
specifications, and other supporting data subsequently filed and approved by the Department of
Environment, Health and Natural Resources and considered a part of this permit.
This permit shall be effective from the date of issuance until November 30, 1997, and shall be
subject to the following specified conditions and limitations:
Upon completion of construction and prior to operation of this permitted facility, a
certification must be received from a professional engineer certifying that the permitted
facility has been installed in accordance with this permit and the approved plans and
specifications. Mail the Certification to the Permits and Engineering Unit, P.O. Box
29535, Raleigh, NC 27626-0535.
2. The Mooresville Regional Office, telephone number 704/663-1699, shall be notified at least
forty-eight (48) hours in advance of operation of the installed facilities so that an in -place
inspection can be made. Such notification to the regional supervisor shall be made during
the normal office hours from 8:00 a.m. until 5:00 p.m. on Monday through Friday,
excluding State Holidays.
3. This permit shall become voidable if the soils fail to adequately absorb the wastes and may
be rescinded unless the facilities are installed, maintained, and operated in a manner which
will protect the assigned water quality standards of the surface waters and ground waters.

:4. In the event that the facilities fail to perform satisfactorily, including the creation of
nuisance conditions, the Permittee shall take immediate corrective action, including those as
may be required by this Division, such as the construction of additional or replacement
treatment or disposal facilities.
5. The issuance of this permit shall not relieve the Permittee of the responsibility for damages
to surface or groundwaters resulting from the operation of this facility.
6. Any sludge generated from these treatment facilities must be disposed of in accordance with
General Statute 143-215.1 and in a manner approved by the North Carolina Division of
Environmental Management.
7. Diversion or bypassing of the untreated groundwater from the treatment facilities is
prohibited.
i . T"ne faculties shail be properly maintained and operated at all times.
2. Upon classification of the facility by the Certification Commission, the Permittee shall
employ a certified wastewater treatment plant operator to be in responsible charge (ORC) of
the wastewater treatment facilities. The operator must hold a certificate of the type and
grade at least equivalent to or greater than the classification assigned to the wastewater
treatment facilities by the Certification Commission. The Permittee must also employ a
certified back-up operator of the appropriate type and grade to comply with the conditions
of Title 15A, Chapter 8A, .0202. The ORC of the facility must visit each Class I facility at
least weekly and each Class II, III, and IV facility at least daily, excluding weekends and
holidays, and must properly manage and document daily operation and maintenance of the
facility and must comply with all other conditions of Title 15A, Chapter 8A, .0202. Once
the facility is classified, the Permittee must submit a letter to the Certification Commission
which designates the operator in responsible charge within thirty days after the wastewater
treatment facilities are 50% complete.
3. The facilities shall be effectively maintained and operated as a non -discharge system to
prevent the discharge of any wastewater resulting from the operation of this facility.
111. MONITORING AND REPQRITNG REQUIREMENTS
1. Any monitoring deemed necessary by the Division of Environmental Management to insure
surface and ground water protection will be established and an acceptable sampling
reporting schedule shall be followed.
2. Noncompliance Notification:
The Permittee shall report by telephone to the Mooresville Regional Office, telephone
number 704-663-1699, as soon as possible, but in no case more than 24 hours or on the
next working day following the occurrence or first knowledge of the occurrence of any of

a. Any occurrence at the wastewater treatment facility which results in the treatment of
significant amounts of wastes which are abnormal in quantity or characteristic, such
as the dumping of the contents of a basin or tank; the known passage of a slug of
hazardous substance through the facility; or any other unusual circumstances.

b. Any process unit failure, due to known or unknown reasons, that renders the
facility incapable of adequate wastewater treatment such as mechanical or electrical
failures of pumps, aerators, compressors, etc.
c. Any failure of a pumping station, sewer line, or treatment facility resulting in a by-
pass directly to receiving waters without treatment of all or any portion of the
influent to such station or facility.
d. Any time that self -monitoring information indicates that the facility is not in
compliance with its permit limitations.
Persons reporting such occurrences by telephone shall also file a written report in letter
form within 15 days following first knowledge of the occurrence. This report must outline
the actions taken or proposed to be taken to ensure that the problem does not recur.
Prior to construction of the infiltration gallery, the Permittee shall submit a site map that
delineates the exact location of the infiltration gallery. This map should be submitted to the
Mooresville Regional Supervisor.
2. All components of the groundwater recovery, treatment and disposal system shall be
properly weather -proofed to prevent freezing and failure of the system.
3. The influent and effluent from the treatment system shall be sampled once every two (2)

groundwater quality. The wells shall be constructed such that the water level in the well is
never above or below the screened (open) portion of the well at any time during the year.
However, the exact location and construction details for these wells shall be approved by
the Mooresvile Regional Office, from which a well construction permit must be obtained.

Facilities having a rating of one through four points, inclusive,
do not require a certified operalor. Classification of all other
facilities requires a comparable grade operator in responsible
charge.
Facilities having an activated sludge process will be assigned
a minimum classification of Class 11.
Facilities having treatment processes for the removal of metal
or cyanide will be assigned a minimum classification of Class II.
Facilities having treatment processes for the biological removal
of phosphorus will be assigned a minimum classification of Class
III.
In -plant processes and related control equipment which are an
inlegraf part of industrial production shall not be considered waste
treatment, Likewise, discharges of wastewater from residences
having a design flow of 1,000 gpd or less, shall not be subject to
rating.
